What’s new
The 2018 Lexus GS 450h carries over unchanged from 2017.
Vehicle overview
For the most part, owning a sporty luxury sedan means sacrificing fuel economy. But the 2018 Lexus GS 450h is a notable exception. This hybrid luxury sedan is enjoyable to drive and saves you gas at the same time.
For sale near San Diego, CA
From economical to sporty, there's a Lexus GS model that appeals to most luxury sedan buyers. The 450h's hybrid powertrain combines a 3.5-liter V6 with large electric motor producing a healthy 338 combined horsepower. The rear-wheel-drive 450h can accelerate from zero to 60 mph in a claimed 5.6 seconds and return combined 31 mpg (29 city/34 highway).
And while other manufacturers have sacrificed dynamics for hybridization, the GS 450h maintains its performance capability thanks to its sporty handling. The rest of the 450h is very similar to the GS 350, including the large 12.3-inch infotainment display, navigation system, and plenty of standard and optional features.
On the downside, the 450h's pricing is much higher than a comparably equipped gasoline-only GS 350 as well as starting prices for rivals such as the BMW 530e plug-in hybrid and Acura RLX Sport Hybrid. We're also not fond of the 450h's infotainment interface. But on the whole, the 2018 Lexus GS 450h is a smart pick if you're looking to get high levels of luxury, performance and fuel economy in one package.

Trim tested
Each vehicle typically comes in multiple versions, although trim levels share many aspects. The ratings in this review are based on our full test of the 2014 Lexus GS 450h F Sport (3.5L V6 hybrid | CVT automatic | RWD)
Scorecard
Overall | 7.4 / 10 |
Driving | 7.5 |
Comfort | 8.0 |
Interior | 8.5 |
Utility | 6.5 |
Driving
7.5Lexus says the GS 450h is the quickest GS you can buy, but our tests show it's slightly slower than the standard car. Its handling is intuitive and well balanced, though it lacks the outright grip of F Sport-equipped cars. Still, this is a solid performer with rewarding driving character.
Acceleration
7.0Acceleration is smooth and uninterrupted with 60 mph arriving in only 6 seconds, which is average for a midsize luxury sedan. The GS feels rapid and responsive thanks to abundant torque.
Braking
7.0Overall braking composure is good, but very savvy drivers will notice that the brake pedal feels a bit inconsistent at low speeds. In our panic-braking test, the GS 450h stopped from 60 mph in 122 feet, which is average for the segment.
Steering
7.0The Lexus GS 450h goes where you point it for most situations. The steering effort is adjustable, but the feedback is minimal. Overall, the sedan strikes a good balance between everyday usability and available performance in its steering tuning.
Handling
7.0More capable than it needs to be, the GS 450h will hustle when it's asked but never feels uncomfortable as a result. It offers higher limits than most drivers will explore. But its limits are lower than those of non-hybrid cars in the segment.
Drivability
7.5The GS 450h, because of its abundant torque, is responsive and easy to drive, which is unusual in a car equipped with a continuously variable automatic transmission (CVT). It's also very quiet.
Comfort
8.0A luxury hybrid with sporting intentions isn't a car we'd expect to sacrifice all else in the name of comfort, but the GS 450h does a nice job of splitting the difference. It's amply comfortable when that's what you want.
Seat comfort
7.5The heated and ventilated front leather seats are a highlight. Comfort is good even after extended driving. Adjustments are abundant but not always intuitive. There's excellent thigh support, though some drivers might find the seat bottoms a bit flat.
Ride comfort
8.5An active, adaptive variable suspension (part of the F Sport option) helps this GS 450h split the difference between sport sedan and proper Lexus. The ride is generally smooth and controlled with little harshness on rough roads in Normal mode. Sport+ mode is stiff.
Noise & vibration
8.5There's precious little wind noise, even at high speed, just as you'd expect from Lexus. The powertrain is particularly quiet, and electric mode provides near noise-free motoring below about 25 mph.
Interior
8.5A large, highly functional interior with very good materials and high-quality assembly is slightly offset by a unique but awkward infotainment control setup.
Ease of use
7.5The highlight and downfall of the GS' otherwise logical interior is the Remote Touch infotainment interface. It's a novel approach, but it's confusing and inconsistent and demands too much attention.
Getting in/getting out
8.0In traditional Lexus fashion, the GS is built for real people. The doors are wide, the sills are narrow, and the seats are relatively high. It's very easy to get in and out of.
Roominess
8.5The GS is a big car, and the interior reflects that. Front passengers will enjoy lots of hip-, leg- and headroom as well as shoulder room. The story is the same in the back unless you are very tall.
Visibility
8.5There's excellent forward visibility thanks to small pillars and minimal blind spots. Front and rear parking sensors and a rear camera take care of the rest. Fantastic high-beam headlights on the open road.
Quality
8.0Lexus cars are built to a high standard, and the GS 450h is no exception. The interior materials are stunning, and the controls offer precise feel. The body panels are well matched, and gaps are consistent. It's what we expect at this price.
Utility
6.5The sedan's useful variety of interior storage options is offset by a small trunk and a back seat that doesn't fold down.
Small-item storage
It has a useful glovebox, two cupholders ahead of the shifter and a medium-size center console that opens wide. The front door pockets are a decent size but won't hold a water bottle. The rear door pockets are small but will fit a bottle. The rear center armrest has a storage bin and cupholders.
Cargo space
Because of the hybrid battery pack, the trunk offers just 13.2 cubic feet of space, which isn't much more than what you get from a typical compact sedan. The rear seatbacks don't fold either.
Child safety seat accommodation
Has two pairs of LATCH anchors at the bottom and three top-tether anchors along the top. Bottom LATCH anchors are tightly recessed between the seat cushions, though. Rear legroom is generous enough for most rear-facing seats to fit, but tall front occupants might still have to scoot up some.
Which GS 450h does Edmunds recommend?
With just one trim level, the GS 450h is very easy to buy. There are stand-alone options such as a Mark Levinson surround-sound audio system, a power trunklid and parking sensors, and they're all relatively affordable. If you're looking to get something a little more aggressively styled, consider the GS 450h F Sport.

2013 GS450h Update 2Q20
5 out of 5 starssdgolwn, 01/11/2014
2013 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
Purchased via Lexus' December to Remember event for $15K off sticker, so made purchase much easier. Price for this car is otherwise high for what it is.
Black with flaxen seats and lux package for $60K--Because of valuation, was considering 2014 ES300h with Ultra, but this price made the GS450h more palatable.
Beautiful car. Good mileage for such a large sedan. Great drive.
Traded … Infiniti FX35 (2009). Liked car, but dealer experience was awful. San Diego Lexus is great and complete opposite.
I recommend this car to anyone--it has surprised even me how much I love it. The power in Sport + is awesome!
Just passed year four, and still in love with the vehicle. What a pleasure to drive. Over summer took it to the mountains and it performed excellently.
January 2019 update: I am tempted to buy a new car, but still love this one and with only 26K, hardly seems necessary. Still very happy with decision.
The only criticism is Lexus needs to update/improve its user interface; there is lots of room for improvement, and is true of my NX, too.
There was but one repair of late; that is, the driver's door actuator went south, but Lexus covered it. This has happened on previous Lexii have owned, so seems to be known failure point. Other that that, all is still like new. Early 2020 passenger door actuator go out and Lexus would not cover it. I emailed my thoughts to them--no reply. The car now has almost 33K miles, and still drives wonderfully. As of now, about 36K. Still no issues, though time for tires. Still love the car.
Fast Luxurious Car With Great Fuel Economy!
5 out of 5 starsClifford Tyler, 08/28/2018
2018 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
I've owned this special order base model hybrid car for six months, and am wildly impressed with its combination of quick performance, sporty road handling and excellent fuel economy. Although EPA rated at 29 mph city and 34 mph highway (31 combination), 38 mph highway, and 35 mph combination is easy to reach, if driven correctly. Cabin is very quiet, interior has high quality fit and … finish, Navigation panel map is huge, and the Mark Levinson sound system is incredible. Technology and infotainment require a learning curve. Well worth the extra price over the GS 350 of ES models.
Best New Car I've Ever Owned
5 out of 5 starsPhil W., 05/20/2017
2013 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
I have a 2013 Lexus GS450h with Luxury Package and Precollision with Dynamic Radar Cruise Control and I have to say this is the best car I've ever owned. First of all, I LOVE driving a Hybrid and second, I LOVE the performance on this thing. 340HP and I average just a hair shy of 30MPG. I'm going to take it to Thunder Hill Race Way next month to show off to the Miata and Lotus guys... my … tires are low so I figure I'd wear it out even further before putting on a new set (LOL). Third LOVE for this car is the equipment... The 18 way adjustable seats are TO DIE FOR. I am 5'6" and will never buy another car without leg extenders and adjustable side bolsters and butterfly headrest. Triple LED headlamps are also awesome. Originally, they were too low so it took me about 30 minutes to figure out how to slightly adjust the beams higher and now they are perfect. My daughters, 8 and 4, are so spoiled from rear door and windshield sunshades and pleathra of buttons in the center armrest. I put them into my BASE Tacoma truck and she thought it was FANCY and HIGHTECH because of cloth seats and manual windows. Lastly, Dynamic Radar Cruise is another thing I love. If every car on the road had it, we can all set the cruise control at 75 MPH on the freeway and CRUISE on the freeway substantially reducing congestion and save gas at the same time from drafting each other and reduction in speed up/slow down. If this isn't a thing already, IT SHOULD BE. Thank you for reading!
39 months later and love the car even more
5 out of 5 starssdgolwn, 10/12/2014
2013 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
Update: 04/2020: I still love and recommend the car. That said, it did suffer its first failure of a passenger door actuator. Having owned several TMC/Lexus products, it is sadly not uncommon. The dealer quoted almost $800, but a local shop did it for $535, using OEM parts. 9/2017 -- Just had 20K service and nothing to report, which is why I love Lexus. 03/17: The car had to have … the first repair of any kind since purchase: The door locking mechanism/actuator required replacement. The car is still under warranty until 12/28/17, so no cost. I've had the car almost 48 months now and actually love it more than I did in the beginning. As [twice] previously mentioned, I do not drive much, as I live in downtown San Diego, mostly walking to destinations. I am averaging 29 in town, with 35-36 on the highway when driving to Palm Springs or Los Angeles. I have found driving in ECO mode is usually fine, unless I am in the desert (my car is black, so require full a/c there). Sport + is a totally fun experience, and I like that I can have it when I want it. The service experiences at San Diego Lexus were great--what a treat over the previous Infiniti experience. I recognize that this is a unique car, and most will buy the 350 rather than the 450h; but they are missing out on a true sleeper! This car is surprisingly fun to drive, comfortable and economical. It's not cheap to buy, but if one buys it at the end of the year like I did, one can make it a value close to that of the 350. I highly recommend this car.
